ANDREWSIEGEL,0fHydePaIk,iI1thGCOImtyOf Norfolk, State of Massachusetts,have invented a certain new and useful Improvement in Dies, of which thefollowing is a description sufficiently full, clear, and exact to enableany person skilled in the art or science to which said inventionappertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which- VFigure 1 is a side elevation of the upper or movable die; Fig. 2, a sideelevation of the lower or bed die with the stripper in its normalposition and the plunger inserted; Fig. 3, an end elevation of the upperdie; Fig. 4., an end elevation of the lower die,showing the cutter ofthe plunger; Fig. 5, a vertical transverse section of the upper die;Fig. 6, a vertical transverse section of the lower die with the plungerinserted; Fig. 7, a top plan view of the lower die with the plungerinserted; Fig. 8, a bottom plan view of the upper die; Fig. 9, a topplan view of the lower die with the plunger withdrawn; Fig. 10, aperspective view of the blank before being submitted to the action ofthe dies, and Fig. 11 a like view of the blank after it has beensubmitted to the action of the dies.

Like letters of reference indicate corresponding parts in the differentfigures of the drawmgs.

Our invention relates to that class of dies which are employed in themanufacture of axes and similar articles for giving them shape andforming the eyes to receive the handles or 'helve's; and it consists inthe novel construction and combination of parts,hereinafter more fullyset forth and claimed, the object being to produce a more effectivedevice of this character than is now in ordinary use;

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

In the drawings, A represents the bed-die; B, the upper die; G, thestripper, and D the plunger.

The bed-die is provided with a rabbet or dovetail, v, on its lowerside,to fit a corresponding groove in the bed or support (not shown) onrwhichit is mounted, the upper die being also provided with a rabbet ordovetail, (l, on its upper side,to enable it to be secured to thecross-head or plunger of the drop-press.

(Not shown.) Projecting upwardly at either end of the bed-die there is astandard, E, provided with a vertical groove, m. A vertical groove, H,which is rectangular in cross-section, is formed in the upper portion ofthe beddie, said groove running longitudinally and centrally of the bodyof the die, and opening outwardly through the standards E. Disposed insaid groove, and arranged horizontally therein, is a plunger, D,provided with a longitudi= nal groove, 1', in one of its sides, a screw,f, being inserted in the body A,and projecting into said groove, thescrew acting as a stop to prevent the' plunger from being entirelywithdrawn.

The plunger Dis provided at its inner end with a wedge-shaped cutter, J,which is shaped in cross-section at its top, and stands centrally in thegroove H, said cutter being adapted to cut or form the groove or slot-bin the blade portion of the blank K, for receiving the steel of the ax,as shown in Fig. 11.

The stripper C is rectangular in form, and provided centrally at one endwith a stud, Z, which is fitted to work in the slot m of one of thestandards E, and at the other end with a corresponding stud, l, which isfitted to work in a slot, 112., in the other standard E, said lastnamedstud being elongatedto form the handle L. The upper portion of thestripper, at one of its sides, is cut away at either end to form anincline, h, its under portion at the opposite side being also cut awayat either end to form an incline, i, the inclines being arranged inparallelism with each other. A hole, N, is formed in the body of thestripper C, said hole being arranged longitudinally therein, andextending vertically through the center of the same from top to bottom,the

the die B at a, said spring acting contractively to draw the hookagainst a stud or stop, 3 projecting laterally from the body of the die.A vertically-arranged follower, O, is secured in the die B by a screw,12, said follower being adapted to fit loosely in the hole N of thestripper O. Projecting from the lower end of said follower there is avertically-arranged punch, Q, adapted to punch or form the eye w in theblank K.

In the use of our improvement, the dies A B being first properlyadjusted and secured in the press, the plunger D is pushed in until itscutter J projects through the end of the die, as shown in Fig. 7. Theblank K, (shown in Fig. 10,) being first heated, if necessary, is thenplaced edgewise in the hole N of the stripper O, and permitted to restonthe top of the plunger D. The press is then operated to drop the die Band cause the punch Q to enter the blank and punch or form one-half ofthe eye 10, at the same time forcing the blank outward or expanding itand wedging it in the hole N. As the die B descends, the curvedportions 1) of the hooks M strike theinclines h on the stripper 0,thereby forcing the hooks outward until the hooks proper, j, have passedthe stripper, after which they are held in position to engage thestripper by means of the springs k, the hooks proper, j,being drawn bysaid springs inwardly into sockets 0, formed in the upper portion of thedie A, beneath the ends of the stripper,when the die B is raised. Thedie B being down, the punch Q in the blank K, and the hooks M inposition to engage the stripper G, as described, the press is nowoperated to raise the upper die, thereby withdrawing the punch Q fromthe blank and causing the hooks M to turn the stripper on its studs orjournals m, the blank in. the hole N being of course turned with thestripper. After the stripper and blank have been turned, asdescribed,the upper die B is again dropped, causing the punch Q to formor punch the other half of the eyewin theblank, after which the upperdie is again raised, the punch withdrawn from the blank,and the stripperturned by the hooks in substantially the same manner as alreadydescribed, the blank being left in the stripper. The plunger D is nowwithdrawn until stopped by the screw f, thereby bringing the cutter Jinto proper position to form the groove or slot 1), after which the dieB is again dropped, causing the punch Q to enter the eye w and thefollower O to strike the blank K and force it out of the hole N downinto the groove H, the groove 1) in said blank being formed by thecutter J as the blank descends. The groove H in the lower die isslightly wider than the hole N in the stripper, and as the blank strikesthe bottom of said groove it is expanded by the follower O and punch Q,so that when the upper die is again raised the stripper will strip itfrom the punch and leave it in said groove. The upper die, B, beingagain raised and the blank left in the groove H, with the eye 10 punchedand the slot Z formed, the plunger l),which is then in the positionshown in Fig. 9, is forced inwardly until brought into the positionshown in Fig. 7, thereby pushing the blank out of the die A, and leavingthe dies in readiness to repeat the operation. The sides or edges of thestripper O are rounded, and as the die B and its punch Q rise towithdraw the punch from the blank whilc'it remains in the hole N, theblank, being wedged in said hole, will cause the stripper to be carriedupwardly with the punch until the studs or journalsl reach the upperends of the slots m, when the punch will be disengaged from the blank,the

stripper at the same time being turned on its studsZ by the hooks M, anddropped onto the die A, the elevation of the stripper, as described,enabling it to be turned to better advantage than when not elevated.

The handle L is for enabling the stripper to be turned by the workman incase the hooks M for any reason should fail to perform their functionsproperly. It also enables the hooks to be dispensed with, if desired.

The hole N corresponds approximately in horizontal section at any givenpoint with a horizontal section of the blank shown in Fig. 11, taken ata corresponding point before the groove bis formed, said hole beingapproximately of the same shape as a finished ax, and hencecomparatively little labor is required to complete the ax after itleaves the die.

Ve do not confine ourselves to making the groove H wider than the holeN, as the friction produced by pressing the blank into said groove-andonto the cutter J, as described, will be sufficient usually to enablethe punch Q to be withdrawn from the blank when the die B rises, withoutwithdrawing the blank from said groove, the friction between the punchand blank being less than that between the blank and sides of the grooveand cutter after the blank has been forced into the groove by thefollower O, as described. Neither do we confine ourselves to the use ofthe groove H, plunger D, and cutter J, as the bed-die may be madewithout said groove, and the slot b formed in the blank by other means,if desired. One hook M may also be used, instead of two, by arranging itcent-rally of the stripper.

The device may be used in the manufacture of other articles than axes,if desired, and hence we do not confine ourselves to using it for anyspecial purpose.

The plunger D may, if desired, be connected by suitable appliances withmechanism adapted to operate it by power. The stripper L may also beturned by other mechanical means than the hooks M, if preferred.

Having thus explained our invention, what hooks, the stripper beingadapted to be re volved or turned and provided with a hole adapted toreceive the blank to be punched, said hole conforming approximately inshape with the shape of the finished ax or other artiole, and the hookor hooks adapted to engage the stripper as the movable die rises, andturn the stripper and blank, substantially as described.
